Diagnosis. According to Koch’s (1958) hypothesis, this genus is close to Aptila Fåhraeus, 1870 and Asidodema Koch, 1958 based on pronotal shape (subparallel sided; flat disc) and male terminalia (relatively short tegmen; clavae as large as penis). All three genera were previously classified within a single subtribe Aptilina. From Aptila and Asidodema, Anaxius can be distinguished by having widened protarsi and the apical segment of the maxillary palpus enlarged in males. Moreover, it differs from Aptila by the lack of scale-like vestiture on the upper surface of the body, while the relatively reduced prosternum differentiates it from Asidodema (see Koch 1958).

Anaxius was recorded from localities distributed between 874 and 1544 meters in elevation ( Fig. 6View FIGURE 6).

Note. During the present investigation 49 Anaxius specimens were studied. Among this number a total of three females was identified. Because of this the following key includes only the male morphology.
